Energy condition

In relativisticclassical field theories of gravitation, particularly general relativity, an energy condition is one of various alternative conditions which can be applied to the matter content of the theory, when it is either not possible or desirable to specify this content explicitly. The hope is then that any reasonable matter theory will satisfy this condition or at least will preserve the condition if it is satisfied by the starting conditions.

Motivation

In general relativity and allied theories, the distribution of the mass, momentum, and stress due to matter and to any non-gravitational fields is described by the energy-momentum tensor (or matter tensor) . However, the Einstein field equation is not very choosy about what kinds of states of matter or nongravitational fields are admissible in a spacetime model. This is both a strength, since a good general theory of gravitation should be maximally independent of any assumptions concerning nongravitational physics, and a weakness, because without some further criterion, the Einstein field equation admits putative solutions with properties most physicists regard as unphysical, i.e. too weird to resemble anything in the real universe even approximately.

My World

Uh, yeah y'know, shit is wild he, hehCan't complain though I'm aliveHealthy and all a that knahmsayin?Just tryin' to do my thang, praise to allBust it that nigga Slick Rick said, I waited long time sweatin' itI got jerked but now I'm gettin' it, hazy like asthma bizarre disasterStress almost held me down from bein' a masterThe faster preacher, poet, a teacher, it's been so long like MonifahBelieve that I'm needed, in rappin', I breathe thisSome pick up a microphone and can't even achieve thisOscar award winning your shit, I'm bored with itStop copy-catting son(Why?)'Cause your dog did itGet your own lingo, make up your own jingleTen years later you be bitin' my singlePrimo, take it downtown, swing itIntervenin' on the board, sensimil steamin', yeahCatch the vibe like a tribal danceIn the clubs on the low with the boy stanceMoney rubbin' with a shorty got bumped by a chumpTell him, step off, I'm doin' the hump, yeahI say it's my world and I won't stopAnd if you stand in my way you bound to get droppedSome wish that I was gone 'cause they know I'ma winIn a minute, I'll be makin' six G's times tenI'm the computer, printin' out data take notesThen analyze the information and press sendFreaky like porno, Ron Jeremy saw noObstacle or pussy to stop him from bonin' a hoeMe and the mic double troubleChicks look at us like twins, all lovable and huggablePrognosis, on the, mic I choke outHad the same effects from coughin', blowin' smoke outArchitect, rap technician, man listenIt's no doubt you gonna pump this in your systemMy skills ill and all of that aboveConfidence, I'm not worried 'bout a street buzzI'm O.C., who you?
